3M 7010366966 Silicon Carbide Unitized Wheel 12 in

Product Description

The 3M 7010366966 is a 12-inch diameter silicon carbide unitized wheel in the Standard Abrasives 500 Series, designed for light-pressure surface blending, finishing, and polishing. Its soft, conformable density allows the wheel to follow flat and contoured part geometries without gouging or removing excessive material. The open non-woven web construction resists loading, extending abrasive service life in production and job-shop environments. This wheel is installed by machinists, fabricators, and metalworking technicians on bench grinders, angle grinders, or dedicated unitized wheel machines using a separately sold mandrel.

The 500 Series wheel suits applications where strict dimensional tolerances must be maintained after blending or finishing operations. Silicon carbide mineral cuts effectively on ferrous and non-ferrous metals, exotic alloys, titanium, and composites. The wheel runs clockwise or counterclockwise, providing flexibility across different machine configurations. Typical use cases include deburring, light stock removal, surface conditioning, and pre-polish finishing on precision machined or fabricated components where surface integrity is critical.

Key Features

• Soft density construction conforms to flat and contoured surfaces for controlled, precise finishing
• Silicon carbide abrasive mineral is compatible with ferrous metals, non-ferrous metals, exotic alloys, titanium, and composites
• Open non-woven web resists loading for longer service life in sustained use
• Runs clockwise and counterclockwise for compatibility with a wide range of power tools and machines
• Cuts faster than buff-and-blend non-woven products while still delivering fine surface finishes
• Attaches to tool via a unitized wheel mandrel, sold separately

Compatibility

Designed for use with bench grinders, angle grinders, and unitized wheel machines that accept a center-hole wheel mounted on a compatible unitized wheel mandrel, sold separately.

Installation Notes

Installation should be performed by a qualified metalworking technician or fabricator. Power off and disconnect the tool or machine before mounting or removing the wheel. Inspect the wheel for damage before each use and confirm the mandrel and machine spindle speed rating meets or exceeds the wheel speed rating. Wear appropriate personal protective equipment, including eye protection and gloves, during installation and operation.
